Green tea extract for prevention of prostate cancer progression in patients on active surveillance.

Oncotarget 2018 Dec 28;9(102):37798-37806. Epub 2018 Dec 28.

H. Lee Moffitt Cancer Center & Research Institute, GU Oncology MMG, Tampa, FL 33612-9497, USA.

Background: Active surveillance (AS) has evolved as a management strategy for men with low grade prostate cancer (PCa). However, these patients report anxiety, doubts about the possible progression of the disease as well as higher decisional conflict regarding selection of active surveillance, and have been reported to ultimately opt for treatment without any major change in tumor characteristics. Currently, there is a paucity of research that systematically examines alternate strategies for this target population. Read More

RNA-based markers in biopsy cores with atypical small acinar proliferation: Predictive effect of T2E fusion positivity and MMP-2 upregulation for a subsequent prostate cancer diagnosis.

Prostate 2019 Feb 7;79(2):195-205. Epub 2018 Oct 7.

Medical Faculty, Medical Biology Department, Uludag University, Gorukle, Bursa, Turkey.

Background: Atypical small acinar proliferation (ASAP) is a precursor lesion of prostate cancer (PC), and PC develops from this suspicious focus or an unsampled malignant gland nearby. However, PC-related molecular alterations that could guide the timing of repeat biopsies and help monitor PC risk in ASAP-diagnosed patients have not been investigated. The purpose of this study was to first investigate the expression of seven different PC-related RNAs that included serine 2 (TMPRSS2): erythroblastosis virus E26 oncogene homolog (ERG) gene (TMPRSS2-ERG, T2E) fusion, alpha-methylacyl-CoA racemase (AMACR), kallikrein related peptidase 3 (KLK3), androgen receptor (AR), prostate cancer specific antigen 3 (PCA3), and matrix metalloproteinases (MMP)-2 and 9.

Atypical small acinar proliferation and two or more cores of high-grade intraepithelial neoplasia on a previous prostate biopsy are significant predictors of cancer during a transperineal template-guided saturation biopsy aimed at sampling one core for each 1 mL of prostate volume.

Res Rep Urol 2017 21;9:187-193. Epub 2017 Sep 21.

Department of Urology, Nara Medical University.

Objective: The objective of this study was to evaluate whether high-grade prostatic intraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP) predict prostate cancer (PCa) during repeat transperineal template saturation biopsy with a high number of cores per prostate volume in patients with persistent clinical suspicion of PCa who underwent at least one previous negative transrectal ultrasound (TRUS)-guided biopsy.

Methods: We retrospectively evaluated 135 consecutive patients with persistent clinical suspicion of PCa, despite a set of negative TRUS-guided biopsies and increasing prostate-specific antigen levels; abnormal findings on digital rectal examination, TRUS, or magnetic resonance imaging; previous biopsy showing HGPIN; and previous biopsy showing atypical glands. Transperineal template saturation biopsy (TTSB) was performed at 5mm intervals to sample one core for each 1 mL of prostate volume. Read More

Typing the atypical: Diagnostic issues and predictive markers in suspicious prostate lesions.

Crit Rev Clin Lab Sci 2017 08 22;54(5):309-325. Epub 2017 Aug 22.

c Department of Urology and Renal Transplantation , University of Foggia , Foggia , Italy.

As much as 5% of prostate biopsies yield findings equivocal for malignancy even for skilled uropathologist; such "grey zone" lesions have been addressed in many ways, although the acronym ASAP (atypical small acinar proliferation) is the most widely used when referring to an atypical focus suspicious, but not diagnostic, for malignancy. Since the introduction of this diagnostic category more than 20 years ago, debate has ensued over its histological characterization and clinical significance. Pathology reporting of ASAP, commonly based on strict morphological criteria and traditional immunohistochemical markers such as basal cell antibodies, has been improved by recent availability of novel immunohistochemical markers such as AMACR and ERG.

The role of the serum testosterone levels as a predictor of prostate cancer in patients with atypical small acinar proliferation at the first prostate biopsy.

Asian J Androl 2018 Jan-Feb;20(1):15-18

Department of Urology, Polytechnic University of Marche, Ancona 60126, Italy.

The current literature does not support the usefulness of clinical markers on predicting which patients with atypical small acinar proliferation (ASAP) are more likely to progress to prostate cancer (PCa). Androgens have long been considered to be the potential risk factors for PCa. However, the role of testosterone is controversial. Read More

Atypical Small Acinar Proliferation and High-grade Prostatic Intraepithelial Neoplasia in the Era of Multiparametric Magnetic Resonance Imaging: A Contemporary Review.

Urology 2017 Sep 21;107:5-10. Epub 2017 Apr 21.

University of Melbourne, Department of Surgery, Austin Health, Melbourne, Australia; Department of Surgical Oncology, Peter MacCallum Cancer Centre, Melbourne, Australia; Olivia Newton-John Cancer Research Institute, Melbourne, Australia.

Multiparametric magnetic resonance imaging (mpMRI) has added to the armamentarium for the diagnosis and surveillance for organ-confined prostate cancer. Atypical small acinar proliferation and high-grade prostatic intraepithelial neoplasia (HGPIN) are premalignant prostatic lesions. The management of such lesions remains contentious, and the addition of mpMRI introduces further uncertainty, given its ability to pick up indolent lesions and its use in targeted biopsy. Read More

Diagnostic Difficulties With Atrophy, Atypical Adenomatous Hyperplasia, and Atypical Small Acinar Proliferation: A Systematic Review of Current Literature.

Clin Genitourin Cancer 2016 10 23;14(5):361-365. Epub 2016 Feb 23.

Department of Clinical Pathomorphology, Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Torun, Bydgoszcz, Poland; Department of Oncologic Pathology and Prophylactics, Poznan University of Medical Sciences and Department of Oncologic Pathology, Greater Poland Cancer Center, Poznan, Poland.

Prostate cancer is the second leading cause of cancer death in men, behind only lung cancer. In some cases, the proper diagnosis of prostatic neoplasia can be challenging, and the differential diagnosis includes atypical nonmalignant lesions such as atrophy, atypical adenomatous hyperplasia (AAH), and atypical small acinar proliferation (ASAP). Atrophy and AAH have a benign clinical outcome, and if detected on needle biopsy or transurethral resection of the prostate, clinical follow-up seems appropriate. Read More

Atypical diagnosis in prostate needle biopsies from a developing country (Philippines): The essential role of a urological pathologist.

Prostate Int 2015 Dec 23;3(4):115-7. Epub 2015 Oct 23.

Institute of Pathology, St. Luke Medical Center-Quezon City, Quezon City, Philippines; Institute of Pathology, St. Luke's Medical Center-Global City, Taguig City, Philippines.

Purpose: Borderline prostatic lesions, with insufficient histomorphologic features, to be definitely diagnosed as prostatic adenocarcinoma (PCa) are often signed out as "atypical glands suspicious for carcinoma" or atypical small acinar proliferation (ASAP). These findings that eventually warrant either immunohistochemical (IHC) studies or a repeat biopsy, prove to be more burdensome to patients in developing countries (such as the Philippines), where health care is not as progressive nor is it an utmost priority. At the same time, in countries like the Philippines, there is a shortage of urological pathologists. Read More

Seminal epithelium in prostate biopsy can mimic malignant and premalignant prostatic lesions.

Actas Urol Esp 2016 Jan-Feb;40(1):17-22. Epub 2015 Oct 26.

Departamento de Patología, Instituto Nacional de Nutrición, Salvador Zubirán Vasco de Quiroga, México D.F., México. Electronic address:

Objectives: In most prostate biopsies, the seminal epithelium is easily recognised because it meets characteristic histological criteria. However, some biopsies can mimic malignant or premalignant prostatic lesions. The aims of this study were to analyse the histological appearance of the biopsies that mimic adenocarcinomas or preneoplastic prostatic lesions, discuss the differential diagnosis and determine the frequency of seminal epithelia in prostate biopsies.

Background: To assess whether the addition of clinical Gleason score (Gs) 3+4 to the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria affects pathologic results in patients who are potentially suitable for active surveillance (AS) and to identify possible clinical predictors of unfavourable outcome.

Methods: Three hundred and twenty-nine men who underwent radical prostatectomy with complete clinical and follow-up data and who would have fulfilled the inclusion criteria of the PRIAS protocol at the time of biopsy except for the addition of biopsy Gs=3+4 and with at least 10 cores taken have been evaluated. One experienced genitourinary pathologist selected those with real Gs=3+3 and 3+4 in only one core according to the 2005 International Society of Urological Pathology criteria. Read More

A 4-mo history of both epigastralgia and back pain was presented in a 39-year-old male. Computed tomography showed right lung nodule and abdominal mass attached to the gastric wall, measuring approximately 30 mm and 70 mm in diameter. Since biopsy samples from the lung and abdomen revealed poorly differentiated adenocarcinoma and malignant tumor, clinicians first interpreted the abdominal mass as metastatic carcinoma, and a right lower lobectomy with following resection of the mass was performed.

Prostate atypia: does repeat biopsy detect clinically significant prostate cancer?

Prostate 2015 May 16;75(7):673-8. Epub 2015 Jan 16.

Urology Division, Hartford Hospital, Hartford, Connecticut, USA.

Background: While the treatment pathway in response to benign or malignant prostate biopsies is well established, there is uncertainty regarding the risk of subsequently diagnosing prostate cancer when an initial diagnosis of prostate atypia is made. As such, we investigated the likelihood of a repeat biopsy diagnosing prostate cancer (PCa) in patients in which an initial biopsy diagnosed prostate atypia.

Methods: We reviewed our prospectively maintained prostate biopsy database to identify patients who underwent a repeat prostate biopsy within one year of atypia (atypical small acinar proliferation; ASAP) diagnosis between November 1987 and March 2011. Read More
